Seems it's better like below.
s/Three virtual MSRs added/Add three virtual MSRs ?
mitigations. They are enumerated in an architectural way. Try to
access the three MSRs to ensure the behavior is expected:
Specifically,

1. below three cases should cause #GP:
  * access to a non-present MSR
  * write to read-only MSRs
  * toggling reserved bit of a writeable MSR

2. rdmsr/wrmsr in other cases should succeed

3. rdmsr should return the value last written
